hold the glass in the frame, this holding action being of such nature that while the glass is pressed firmly against the frame there is no tendency for the same to splinter or chip at the edges.

A further object is to furnish a holding means of the kind in question which is capable of ready application and is, therefore, very inexpensive in use.

Other objects and advantages of the invention will become obvious as the description proceeds.

It has hitherto been usual to secure sheets of glass in iron window frames by means of pins or the like. These pins are inserted lnto holes which are drilled in the cross bars of the frame, and are of such length that they project laterally beyond the cross bars, these projecting portions thrusting against the glass. If the holes in the cross bars are positioned in such manner that the pins thrust relatively strongly. against the glass, there is a certain danger of the glass chipping at the edges or even becoming broken entirely when thepins are inserted into position. If on the other hand the holes are somewhat further away fro-m the glass, so that the latter is held merely loosely by the pins, the glass is capable of a certain movement in the frame and is also liable to become broken upon the application of a strong pressure.

The drilling of the holes in the cross-bars of the frame is not only a lengthy matter but is not always simple to perform, at least with the proper degree of accuracy, so that accordinglyithe mounting of a sheet of glass with the assistance of the pins hltherto 1n use is both tedious and expensive, as at least four borings are necessary for each sheet or pane, and as a. matter of fact t 1s usual to provide eight borings 1f the sheet or pane-1s to be securely held at all four edges. I

According' to the invention these disadvantages are overcome by the use of a fastening means which renders the drilling of the cross bars entirely unnecessary, and enables in position on a window bar, which is shown 386,367, and in Germany December 8, 1927.

the sheets of glass to be secured in position in rapid and secure manner. lVhen the glass is being secured in the frame it is quite within the choice of the workman to apply the fastening means in such manner that the glass pressed with any desired degree of tightness against the frame.

According to the invention the fastening means in question consists of a resilient clip, which is placed over the bars of the window frame, and possesses lateral projections thrusting against the glass. The clips by reason of the spring pressure are pressed in such fashion against the two sides of the bars that the same are firmly held by friction.

' The clips are assisted in their hold on the bars by reason of the fact that teeth or serrations are furnished on the arms of the clips, these teeth or serrations being pressed by the resiliency of the clips against the surface of the bar.

The invention will now be described more fully with reference to the accompanying drawing, which shows two different embodiments by way of example.

Fig. 1 shows the clip in one form of embodiment when applied to a bar of the window frame, the bar itself being shown in section.

Fig. 2 is a view of the clip itself,

Fig. 8 being a section along the line 3-3 in Fig 1.

Fig. 4 is the perspective view of a modified form of embodiment of the clip,

Fig. 5 the clip according to Fig. 4 mounted in section,

Fig. 6 a top view of the clip acording to Fig. 4c, and i Fig. 7 the part of a window frame in plan.

Referring now to the drawing, the holding 9G means consists of a Ushaped clip a, which is stamped out from resilient sheet steel or steel. band.. The clip itself may be of any desired width, although the preferred size will be one-third or one-half of an inch in length. In the embodiment according to Figs. 13 the arms of the clip are of equal length, while the distance between the same is equal to the thickness of a rail extended laterally from the window frame bar 6 at its thinnest point.

" F gsthe end fo he emits a The ends 7 of the two arms are bent off laterally at c at right angles or at an obtuse angle, and are folded over insuch manner that the edges (Z of these ends lie within the clip, projecting inwardly to a slight extent beyond the straight vertical portions of the arms. The edges (Z are bevelled so as to form a knife edge.

If the sheets or panes of glass 0 are to be mounted in the iron window frames 5/, the same are placed against the flange 71. of the frame bar 6 in the usual manner with or without a packing, in which connection it is possible to employ for each edge of the glass 6 any desired number of clips. The clips are sin'iply placed in the desired number over the rail of bar 7). In securing the clips theends of the arms are pressed somewhat apart, for which purp -rc it is possible to employ a pair of pliers or Y other suitable tool. Theclip with the forced apart is placed over the rail of bar 72 until the points 2 40f the lateral projections f enter into Contact with the glass 6 and press against the same. lVhen the clip is placed in this mann r over the bar rail, the knife edges (Z pass lightly over the sides of the bar rail in the direction of the glass, and immediately the tool holding the armsof the clip apart is removed the knife edges, by reason of the resilient action, are pressed into the skin or the irregularities in the bar rail. \Vhen the tool is removed from the clip 6 the arms of the latter thrust against the rail of the window frame bar 5 at the upper .end thereof and are maintained in frictional .contact with the bar by reason of the resiliency of the clip. so that in this manner and as a result of the gripping action of the knife edges (5 the clip a is held von the *bar 6 in a perfectly firm manner.

After the clip has been placed in position the clip is preferably given a light blow with a hammer,so that the same will firmly clamp the glass and also move over the rail bar I) to the greatest possible extent. Each sheet of glass 0 may be held at each edge by means of two or more clips and each clip mounted on the bar rail of the window frame (Fig. 7) serves to hold the sheets of glass 0 situated on both sides of the bar rail.

In the embodiment according to Fig. 5 it is assumed that the rail of the window frame bar does not possess a conical form as shown in Fig. 1, but that the lateral faces thereof are practically parallel to each other. It is possible on this type of bar to employ a clip ton t d Wo ing Fis 2, er al o ear P y a l p n t e em od en .ag eer i to g i. I he sa e m nner a 911 i s t 4 may als be employed junction with a window frame bar hav ng a railof the form shown in fig. 1.

I he embod nt of the clip .aec

dingto are also bent laterally at 0 at an obtuse angle. The ends, however, are not folded over in the manner of the previous embodiment. In order in this case to obtain sharp edges for engaging the bar rail, the clips are cut out from the sheet steel or steel band in such manner that the ends are bent laterally at c to form lugs k, which are somewhat broader than the arms of the clip a. The parts of the lugs extending beyond the width of the arms are constructed to form tapered ears or teeth m, which are directed inwardly and when the clip is bent into U-shape project somewhat beyond the plane of the arms. These teeth m function exactly in the same manner as the bevelled edges '(Z in ;the .case of the embodiment according to Figs. 18.

The lugs 70 may be furnished with a U- shaped or other suitable incisiomand the resulting tongue a bent upwardly approximately parallel with the arms, which will enable the clip to be readily grasped by .the tool for the purpose of spreading the arms apart when fitting the clip in position.

In such cases in which glass'is Situated only on one side of the ,ban for example .edge panes, it is pneferable .tO furnish only the one arm of the clip with ,a laterally projecting lug is, leaving the other arm straight so that the same will fit perfectlysnugly against the outside of the bar.
